RAILROAD TIE.

Application led February 5, 1929.

rlhis invention relates to improvements in railroad tics and inoreparticularly to a rein forced concrete tie.

@ne ot its objects is the provision ot a tie oi this character which hasbeen designed to aitord a inore nnitorin distribution ot the load on theballast, to present a greater bearingl snriace, and to etl'ectivelywithstand the stresses ot the l'orces passing' into it.

Another object ot the invention is to provide a comparatively light andinexpensive concrete tie which is constructed 'to retain its position inthe ballast in which it is einhedu ded, and which will materially reducethe V maintenance costs ot street railway and steam tracl lines.

In the accornpanyine,4 drawings .Figure l is a top plan view ot a tieembodyingl my invention. Figure 2 is a side view thereof. Figures 3, 4and 5 are cross-sections on the correspondingly numbered lines inltiignro l. Figure G a side View ot a inedii'ied form oit niy invention.Figure 7 is a cross-section thereot on line il-7, Figure G.

Similar characters ot reference indicate correspendingl parts throughoutthe several vi ewsA My improved tie is preterahly constructed otreintorced concrete and in the embodiment thereof shown in Figures l to5 inclusive, it comprises a central or span portion l0, end portions lland rail-engagingl portions 129 the latter having@ bolts i3 en'ibeddedtherein 'tor anchoring' the rails thereto. The span portion ot the tieis snl'istantially triangular in cross-section, beingfiat acrossitstopgtace, as indicated at 14, and having its opposite sit es or faceslo converging,T downwardly. rlhe top and bottoni corners ot this spanpor" tion are preferably chainitered or flattened, as indicated at lo inFinn re 5.

The end portions ll oi the tie are likewise substantially triani'rjnlar.in cross-section. be ingl tlat across their bottoni tacos 17 andhavinn` their opposite sides i8 converging` npwai-diy. as shown inFigure 3. The top and bottom corners o these portions are alsochaintered, as indicated at 19 in the saine igifire.

The rail-engaging portions 12 are rec Serial No. 337,648.

tangnlar in cross-sectiml and torni between the span portion l() and endportions ll oppositelv tacinpY i'ipripht shoulders Q0 and 2l,respectively which prevent shitting' o1" the tie transvcrscljvf ot thetracks.

ln the inodilied torni ot the invention shown in Figures (i and T thetie 2Q, is et the saine cro section :troni end to cnd as is the spanportion et the tie previously described.

lip this constrnctiein a comparativcly light, strong;y and durable tieproduced which not onlv absorbs the stress ot the tie against theballast, but aliiords an extensive hearing; tace therefor, elinrin tingthe liability ot the ties shittingl in the ballast. @Wing to thecrossscctions ot the span and end portions ot the tie. the latter 'willretain its position in the ballast and be held against shitting' bothlengthwise and crossvrisc thereof. and it will not be disturbed by theforces passing; over the rails. lnrtherinore. the cri "s-section et suchportions resists the conipri on and tension strains produced by thetrains passing over the rails. i

l claim as iny invention :H

l. A railroad tie consisting ot a span portion, rail-engagingl portionsand end portions, the span portion and end portions beineotsubstantially tri angular cross-scction with their bases oppositelydisposed.

2. it. railroad tie consistingl ot a span portion, rail-engaging'portions and end porti-ons the span portion havingI a tia/t top Wall anddownwaidly-converging side walls, the end portions having; tiat bottoniwalls and npnf'ardly-conveiingr side Walls, end the railennaginpjportions being` rectangular in crosssection.

i railroad tie coi'isistinid)- ot a span portion, rail-engan'innportionsand end portions,y the span portion havi a tlat top Wall anddoWnivardly-convergii 5' side walls, the end portions having; flatbottoni Walls and upwardly-converging side Walls, and the railenpgapingportions beinei rectangular in crosssect-ion and forming` `with theadjoiningI span and end portions oppositelytacing1 shoulders disposedtransversely ott the tie.
